Re: Error building qnx cross-gdb 6.3

[Kris Warkentin <kewarken@qnx.com>]

You're going into somewhat uncharted territories here.  We _DO_ cross 
compile gdb targetting qnx but the GNU cvs doesn't have all the files 
yet for remote debugging.  It only has self-hosted, i386 targetting.

If you would like a drop of the full port of the sources, go to 
http://www.qnx.com/download/group.html?programid=11358 and you can find 
compiled binaries and source for gdb-6.2.1.  You may need to create a 
free myQNX account.

I also have 6.3.0 sources if you would like them.  For what it's worth, 
I build gdb under cygwin with 'configure --disable-sim --disable-nls 
--disable-gdbtk --target=i386-nto'

cheers,

Kris
